Abstract

Un aspect de l'invention concerne un écran tactile pour un ordinateur de plongée, cet écran comprenant au moins une unité d'affichage et une unité de saisie tactile transparente placée devant l'unité d'affichage. Selon l'invention, au moins une cavité ménagée dans l'unité de saisie tactile résistive est remplie d'un fluide incompressible électriquement isolant de telle sorte que la sensibilité au toucher soit effective également sous l'eau et sous une pression accrue.
